We introduce the equotip hardness tester and present the relations between the Equotip rebound value (L-value) and the unconfined compressive strength (UCS) for intact rock samples. Based on existing data and the results of our laboratory tests, an equation is derived connecting UCS (MPa) and L-value obtained from single impacts, L_s, and porosity, n (%), using multiple linear regression analysis: it is found that UCS = 0.079 e^<-0.039n> L_s^<1.15>
